Unicorn boy and the slumber party of doom!

Brian Reyes always felt a bit different—even before growing a unicorn horn, discovering a talking muffin, and swallowing the ruler of the Underworld to save his BFF. So when he receives a mysterious invitation for a Unicorn-Only Sleepover, Brian wonders if these fellow magical creatures might help him make sense of his increasingly odd world. Held in an enchanted castle in the clouds, not everything at this glitzy, glamorous party is as it seems, and Brian will have to fend off increasing social anxiety, ignore the negative feelings in his gut, and stay true to himself if he’s going to survive the night!
